The HH520 is a 4 channel handheld data logger/thermometer that accepts Types J, K, T and E thermocouples. Measurement settings and results are shown on the backlit LCD display. Data can be stored in the data logger and then downloaded to the computer or directly saved on the computer through the USB interface in real time. With the exclusive software, recording/ recalling of data and programming of logging parameters can be done directly through a PC. There is a save dialog window in the software where the data file name and file type to save can be selected. There are three types of file format that can be selected: binary file (*.ghf), text file(*.txt) and Excel® format file (*.csv). The .txt file format can be opened by the HH520 software and any other word processor program like Microsoft® Word or Notepad. The .csv file format can be opened by the HH520 software and also by Microsoft Excel.

The *.ghf file uses much less disk space to save the data than the other two file formats, but it can only be used in the HH520 software.

    J: -200 to 1000°C (-328 to 1832°F)

Rated 4 out of 5 by from Value and practical Value and practical. In stock and prompt delivery. Software may need one more option on grid layout: such as smaller checker board squares on the background to identify data point location. A longer USB cable would be better. On Windows XP, each time the logger is manually powered off and on again and then the hardware driver is automatically installed while USB was plugged in, but need to uninstall and install it again one more time to avoid installation issue. This would need to state in the manual.

Hello, is the only way to record data from the logger through the SE520 software? I want to monitor the temperature and set alarms programmatically. Is there some kind of API?

Asked by: Vatsan
Omega provides the Software for the HH520 so customers can easily capture data then transfer and store. Omega does not have additional interfacing programs or is able to offer support for 3rd party Software or customer developed programs.

How/where to adjust sampling rate 2 samples/sec - to be recorded - I can find 1 sample per second only ?

Asked by: HH520 user
Hi HH520 user The fastest logging rate is once/ sec. 2 samples per sec on the product page refers to the scan rate of the logger. Best regards OMEGA

Hello, I know that Omega does not offer any API to access the data in the logger apart from the software SE520. However, I saw some discussions online, where it seems like you sent the customer the specific protocols for their device. Could I get one?

Asked by: Vatsan
Thank you for your inquiry. E-mail for protocols.
